<div><p>This section describes how to restore an HBase backup set that has been backed up to the original or a new location.</p>
<div class="section"><h4 class="sectiontitle">Context</h4><p>Backup copies, replication copies, archive copies, or imported copies can be used for restoration. Restoration to the original location or a new location is supported. Note that restoration to the original location using a replication copy is not supported, and restoration to the original location is not supported after a replication copy is archived.</p>
